Revert "ALSA: usb-audio: Drop superfluous interface setup at parsing"
commit 16f1f838442dc6430d32d51ddda347b8421ec34b upstream.
This reverts commit ac5e2fb425e1121ceef2b9d1b3ffccc195d55707.
The commit caused a regression on Behringer UMC404HD (and likely
others). As the change was meant only as a minor optimization, it's
better to revert it to address the regression.
